Abstract

La présente invention concerne une technique d'établissement d'une trajectoire logique entre deux serveurs dans un réseau de temporisation coordonné d'un environnement de traitement. La technique consiste à échanger des paires de messages de commande et de réponse par un serveur et un serveur rattaché, via une liaison physique. Le serveur transmet un message de commande à un serveur rattaché pour établir une trajectoire logique de protocole de temporisation de serveur (STP) et reçoit une réponse du serveur rattaché. La technique comprend également la réception par le serveur d'une demande émise par le serveur rattaché, visant à établir une trajectoire logique STP avec le serveur, et l'émission d'une réponse à la demande du serveur rattaché. Une trajectoire logique entre le serveur et le serveur rattaché est établie si la réponse du serveur rattaché indique que la demande du serveur a été acceptée par le serveur rattaché et si la réponse du serveur indique que la demande du serveur rattaché a été acceptée par le serveur.
